Abstract

Practical scatter factor formulae, dealing with conditions where the population standard deviation is unavailable and where fatigue test results are incomplete, are presented to determine the safe fatigue crack initiation and propagation lives from the results of a single full-scale test of a complete structure. A new durability model incorporating safe life and damage tolerance design approaches is derived to assess the first inspection period for structures. New theoretical solutions are proposed to determine the S a  − S m  − N surfaces of fatigue crack initiation and propagation. Prediction techniques are then developed to establish the relationship equation between safe fatigue crack initiation and propagation lives with a specific reliability level using a two-stage fatigue damage cumulative rule.
